I moved my 180 by placing it on an appliance dolly. I had cut a 6'6" X 30" plywood board and laid styrofoam on it before we arrived to pick it up. The tank was then placed on it and strapped. We rolled it down the sidewalk but carried it up stairs using the handles of the dolly and the plywood on the bottom. I then strapped the dolly to the trailer. It went very smoothly. I had 4 large guys including myself. It went without a hitch. (at least so far since I haven't filled it).
